const (
	// GasUpdatePeriodBlocks is the block interval at which we report gas fee changes.
	GasUpdatePeriodBlocks = 10

	// GasPriceFactor is a multiplier applied to the gas amount before dividing by the gas
	// limit to determine the gas price, and later used as a divisor on the final fee -
	// this avoid the integer division going to zero, and can be thought of as the
	// reciprocal of the gas price precision.
	GasPriceFactor = uint64(1e9)

	// GasLimit is the default gas limit we will use for all outbound transactions.
	GasLimit = 200000

var CosmosAssetMappings = []CosmosAssetMapping{
	{
		CosmosDenom:    "uatom",
		CosmosDecimals: 6,
		DDChainSymbol:  "ATOM",
	},
}

CosmosAssetMappings maps a Cosmos denom to a DDChain symbol and provides the asset decimals CHANGEME: define assets that should be observed by DDChain here. This also acts a whitelist.

var CosmosSuccessCodes = map[uint32]bool{
	errortypes.SuccessABCICode:                true,
	errortypes.ErrTxInMempoolCache.ABCICode(): true,
	errortypes.ErrWrongSequence.ABCICode():    true,
}

CosmosSuccessCodes a transaction is considered successful if it returns 0 or if tx is unauthorized or already in the mempool (another Bifrost already sent it)

Types

type CosmosAssetMapping 

type CosmosAssetMapping struct {
	CosmosDenom    string
	CosmosDecimals int
	DDChainSymbol  string
}

func GetAssetByCosmosDenom 

func GetAssetByCosmosDenom(denom string) (CosmosAssetMapping, bool)

func GetAssetByDdchainSymbol added in v0.2.0 

func GetAssetByDdchainSymbol(symbol string) (CosmosAssetMapping, bool)

type CosmosBlockScanner 

type CosmosBlockScanner struct {
	// contains filtered or unexported fields
}

CosmosBlockScanner is to scan the blocks

func NewCosmosBlockScanner 

func NewCosmosBlockScanner(cfg config.BifrostBlockScannerConfiguration,
	scanStorage blockscanner.ScannerStorage,
	bridge ddclient.DdchainBridge,
	m *metrics.Metrics,
	solvencyReporter SolvencyReporter,
) (*CosmosBlockScanner, error)

NewCosmosBlockScanner create a new instance of BlockScan

func (*CosmosBlockScanner) FetchMemPool 

func (c *CosmosBlockScanner) FetchMemPool(height int64) (types.TxIn, error)

FetchMemPool returns nothing since we are only concerned about finalized transactions in Cosmos

func (*CosmosBlockScanner) FetchTxs 

func (c *CosmosBlockScanner) FetchTxs(height, chainHeight int64) (types.TxIn, error)

func (*CosmosBlockScanner) GetBlock 

func (c *CosmosBlockScanner) GetBlock(height int64) (*tmtypes.Block, error)

GetBlock returns a Tendermint block as a reference to a ResultBlock for a given height. As noted above, this is not necessarily the final state of transactions and must be checked again for success by getting the BlockResults in FetchTxs

func (*CosmosBlockScanner) GetHeight 

func (c *CosmosBlockScanner) GetHeight() (int64, error)

GetHeight returns the height from the lastest block minus 1 NOTE: we must lag by one block due to a race condition fetching the block results Since the GetLatestBlockRequests tells what transactions will be in the block at T+1

type CosmosClient 

type CosmosClient struct {
	// contains filtered or unexported fields
}

CosmosClient is a structure to sign and broadcast tx to Cosmos chain used by signer mostly

func NewCosmosClient 

func NewCosmosClient(
	ddKeys *ddclient.Keys,
	cfg config.BifrostChainConfiguration,
	server *tssp.TssServer,
	ddchainBridge ddclient.DdchainBridge,
	m *metrics.Metrics,
) (*CosmosClient, error)

NewCosmosClient creates a new instance of a Cosmos-based chain client

func (*CosmosClient) BroadcastTx 

func (c *CosmosClient) BroadcastTx(tx stypes.TxOutItem, txBytes []byte) (string, error)

BroadcastTx is to broadcast the tx to cosmos chain

func (*CosmosClient) ConfirmationCountReady 

func (c *CosmosClient) ConfirmationCountReady(txIn stypes.TxIn) bool

ConfirmationCountReady cosmos chain has almost instant finality, so doesn't need to wait for confirmation

func (*CosmosClient) GetAccount 

func (c *CosmosClient) GetAccount(pkey common.PubKey, _ *big.Int) (common.Account, error)

func (*CosmosClient) GetAccountByAddress 

func (c *CosmosClient) GetAccountByAddress(address string, _ *big.Int) (common.Account, error)

func (*CosmosClient) GetAddress 

func (c *CosmosClient) GetAddress(poolPubKey common.PubKey) string

GetAddress return current signer address, it will be bech32 encoded address

func (*CosmosClient) GetChain 

func (c *CosmosClient) GetChain() common.Chain

func (*CosmosClient) GetConfig 

func (c *CosmosClient) GetConfig() config.BifrostChainConfiguration

GetConfig return the configuration used by Cosmos chain client

func (*CosmosClient) GetConfirmationCount 

func (c *CosmosClient) GetConfirmationCount(txIn stypes.TxIn) int64

GetConfirmationCount determine how many confirmations are required NOTE: Cosmos chains are instant finality, so confirmations are not needed. If the transaction was successful, we know it is included in a block and thus immutable.

func (*CosmosClient) GetHeight 

func (c *CosmosClient) GetHeight() (int64, error)

func (*CosmosClient) IsBlockScannerHealthy 

func (c *CosmosClient) IsBlockScannerHealthy() bool

func (*CosmosClient) OnObservedTxIn 

func (c *CosmosClient) OnObservedTxIn(txIn stypes.TxInItem, blockHeight int64)

OnObservedTxIn update the signer cache (in case we haven't already)

func (*CosmosClient) ReportSolvency 

func (c *CosmosClient) ReportSolvency(blockHeight int64) error

func (*CosmosClient) ShouldReportSolvency 

func (c *CosmosClient) ShouldReportSolvency(height int64) bool

func (*CosmosClient) SignTx 

func (c *CosmosClient) SignTx(tx stypes.TxOutItem, ddchainHeight int64) (signedTx, checkpoint []byte, _ *stypes.TxInItem, err error)

SignTx sign the the given TxArrayItem

func (*CosmosClient) Start 

func (c *CosmosClient) Start(globalTxsQueue chan stypes.TxIn, globalErrataQueue chan stypes.ErrataBlock, globalSolvencyQueue chan stypes.Solvency)
